使用 Spring RestTemplate 获取 JSON 对象列表 [英] Get list of JSON objects with Spring RestTemplate

问题描述

我有两个问题:

• 如何使用 Spring RestTemplate 映射 JSON 对象列表.
• 如何映射嵌套的 JSON 对象.

我正在尝试按照 https://bitpay.com/api/rates 的教程使用http://spring.io/guides/gs/sumption-rest/.

I am trying to consume https://bitpay.com/api/rates, by following the tutorial from http://spring.io/guides/gs/consuming-rest/.

推荐答案

也许这样...

ResponseEntity<Object[]> responseEntity = restTemplate.getForEntity(urlGETList, Object[].class);
Object[] objects = responseEntity.getBody();
MediaType contentType = responseEntity.getHeaders().getContentType();
HttpStatus statusCode = responseEntity.getStatusCode();

RequestMapping

@RequestMapping(value="/Object/getList/", method=RequestMethod.GET)
public @ResponseBody List<Object> findAllObjects() {

    List<Object> objects = new ArrayList<Object>();
    return objects;
}

ResponseEntity 是 HttpEntity 的扩展，它添加了一个 HttpStatus 状态代码.在 RestTemplate 以及 @Controller 方法中使用.在 RestTemplate 中，这个类由 getForEntity() 和 exchange() 返回.

ResponseEntity is an extension of HttpEntity that adds a HttpStatus status code. Used in RestTemplate as well @Controller methods. In RestTemplate this class is returned by getForEntity() and exchange().
